Answer: 2and 6 over here are dimensional constants.
Explanation:
The equation provided to us is x = 2t + 6t^2.
From the rules of Dimensional Analysis, the dimention of the RHS has to be equal to the LHS. Hence, Dimention of 2t and 6t^2 has to be equal to that of Length. That means , dimension of 2 and 6 has to be [LT^-1] and [LT^-2] respectively in order to fulfil the above condition.
Hence, 2 and 6 are dimensional constants.
